Thomas Jefferson Smith (born 31 March 1990) is a professional footballer who plays as a defender for A-League club Auckland FC.

[4] He was on the shortlist for the 2008 Wickes Young Apprentice Trophy, given to the best youth player in the Championship,[5][6] but Mark Beevers won the award.

[11] Smith's form for Stevenage led to him getting his opportunity in the Ipswich first-team, he made his debut on 9 August 2008, in a 2–1 home loss to Preston North End at Portman Road.

However, by the time he made his return to first team action, manager Jim Magilton had left the club and been replaced by Roy Keane.

In his absence Gareth McAuley and Damien Delaney formed a solid defensive partnership ahead of deputizing goalkeeper Arran Lee-Barrett.

Smith became the youngest captain in All Whites history after leading the team in a 2–2 draw versus El Salvador on 23 May 2012.
